The Douglas County Sheriff's Department says the driver of a car that crossed the center line and struck 56 year old Jim Johnston on Thursday afternoon near 260th and West Center Road is 82 year old Ruth Jeffers of La Vista.
Investigators say Johnston was riding westbound on the shoulder when Jeffers eastbound Ford Taurus crossed the center line and struck him.  Johnston died at the hospital.
Johnston retired last year as a teacher at Millard West, where he also served as the athletic trainer.
The accident investigation has not been completed and charges will be decided through the Douglas County Attorney some time next week.
